KILN BRACE Filed Oct. 13, 1928 Patented Nov. 10, 1931 UNITED STATES CHARLES A. NELSON, OF EAST BERLIN, CONNECTICUT KILN BRACE Application filed October 13, 1928. Serial No. 312,366.

My invention relates to improvements in kiln braces for use in brick yards for the pur pose of propping or bracing the side wall of the kiln against the adjacent structural. work 5 of timber to be used in lieu of the timber-braces that are in common use, and the object of my improvement is to produce a kiln brace in the form of an all metal structure that is made adjustable as to length to provide for fitting into 10 the desired position; that is provided with an effective locking dog; and that is adapted to be adjusted to the final holding position in substantially the usual manner by means of forceful blows by means of a hammer or the 15 like.

In the accompanying drawings Figure 1 is a side elevation of my imgroved kiln brace, the outer pipe being broken away to show the end of the inner pipe.

Figure 2 is a plan view of part of the showing the shoe and adjacent parts.

Figure 3 is an inside face View of the shoe, the inner pipe that is connected thereto being m shown in section.

"" Figure 4 is a side elevation of a special form of structure that has a second shoe at the other end and that is adapted for other uses than for the kilns in brickyards.

Figure 5 is a fragmentary view in section showing the telescoping end portion of a mod ification of the outside brace member.

My improved kiln brace is adapted primarily for use in bracing the side walls of the kilns in brick yards, and to be used in lieu of the devices at present in common use for such bracing. Such common use involves placing a brick against the side wall by one operator; receiving from another operator a piece of timber for marking as to the len gth required;

and finally cutting-off the needed length and inserting in place against said brick. The outside end of the brace is placed in abutment with the stringer of the wooden frame structure that is adjacent thereto. The final tightening is effected by hammering the brace,

which is initially positioned at an inclination.

In the present device, the out-side end 10 is placed in abutment against the enclosing woodwork structure in substantially the usual manner. Also, the tightening is effected by respectively one-half inch and one inch.

hammering. In lieu of the brick at the innerv end, however, I provlde a shoe 11 and this 1s provided at the top edge portion with an integral lug 12 that is adapted to receive the blows of the hammer. The corner at the bot tom edge of the shoe ll'as shown in Fig. 1 is rounded to facilitate sliding downwardly under conditions of use. The shoe 11 has on the inner side a contacting face 13 that may conform in size and shape to that ofa brick, and in use is positioned with the longer dimension vertical. On the outer face 14 of the shoe 11 are spaced lugs 15 that are-perforated for the pivotal pin 16 for connectingthe adj ace-nt brace member 17 and which, as shown, is the inside member of the brace structure proper. Said inside member 17 telescopes within the outside brace member 18 for effecting the desired ad .justment. The outside member 18' terminates at the outer end in the'contacting end 10 for contacting with the timber in holding.

Locking means for the members 17 and 18 are provided in the form of a dog 19 that has a locking end portion that is selectively entered into one of a set of perforations 20 in the side wall of the inside member 17.

The inside and outside members 17 and 18 are made of iron pipe and the sizes may be A bracket '22 mounted on the end of the outside member 18 serves as the means for operatively supporting the dog 19 by means of upstanding spaced ears 23 and a pivotal pin 24. Under locking conditions the looking end portion of the dog 19 mentioned is positioned across the end of the outer pipe so that the butt end thereof sustains the thrust effect.

Usually the outside members 18 would. be

provided in three lengths, respectively 7 of. In order to provide a good fit for the inside member 17 within the end portion of the outer member 18 the bracket 22 may be provided with an annular end face portion 37 that abuts against the opposed end face of the outer member 18 and has a bore 38 to fit the inside member 17. As a modification, however, the annular end face portion may be omitted, as in the form shown in Fig. 5, in which the bracket 12 has a plain bore for the outside of the outer member 18 and a filler collar 43 is provided for the inside of the end portion of said outer member 18.

I claim as my invention 1. A brace structure for use against the side wall of a kiln in a brick-yard or the like comprising a brace structure proper that is composed of members that have overlapping parts that have sliding en agement for effecting a change in length, one of said mem bers being provided at the free end with a contacting shoe for contacting with said.

wall, locking means constructed and arranged for checking said members against F15 thrust pressure under holding conditions and said shoe having a plain fiat face for being opposed to said wall under contacting conditions, said members being in the form of lengths of pipe of different sizes, the one telescoping within the other, and an annular plug structure being inserted within the larger pipe, the opening therein being such as to provide a sliding fit for the periphery of the smaller pipe.

2. In a brick-yard kiln brace structure, a combination of metal parts consistingof wall-contacting means at the ends and a thrust portion intermediate said means, said thrust'portion being composed of a pair of members arranged to telescope one within the other for changing the effective length, the inner of said members being provided with perforations along the length of one side part, and the outer of said members supporting a locking pin for being entered selectively into said perforations, said members being in the form of pipe lengths of different sizes, the one slipped within the other, a bracket on the end of the outer pipe comprising an annular partthat encircles the pipe end, and spaced lugs projecting outwardly from said annular part serving as the means for supporting said locking pin.

3. In a brick-yard kiln brace structure comprising a thrust structure and a shoe pivotally mounted at one end thereof having avertically elongated contacting face for engagement with a wall structure, an enlargement at the top end of said shoe for receiving hammer blows, and the bottom corner edge of said shoe being rounded to facilitate movement of the shoe responsive to hammer blows on said enlargement.
